SHUT-nan..

SPECIFICATION forming part of Letters Patent N0. 760,764, dated May 24, 1904. Application filed February 23, 1904. Serial No. 194,944. (No model.)

Y To alZZ whom it may concern;

Be it known that I, CLARK D. SrALDrNG, of Baltimore, Maryland, have invented a new and useful Improvement in Shutters, which invention is fully'set forth Ain the following specilication. v

In so-called modern fireproof buildings the window-openings are the vulnerable points at which fires on the exterior gain access to the combustible woodwork, fittings, furniture, and the like within. Fireproof shutters heretofore devised fory closing such openings are seldom used principally for the reasons, it is believed, that those Vwhich open on thev outside objectionably deface the building and thosewhich roll up in recesses contiguous to the window are objectionably expensive andy ,Y not readily and easily operable.

With the object of overcoming these diii- 5 shutters when closed to forma tight joint with the outer edges of the slots at thesides neat finish. to the edge of the window-opening.V

of the window-opening and when the shutters are opened to tightly close the slots through which they slide into the recesses,r thereby excluding rain, snow, dust, te., and givinga Other important features of the invention will be referred to in describing the invention in connection with the laccompanying drawings,\in which- Figure 1 is an outside elevation ofL a part of the wall of a building, showing a windowopening tov which my invention is applied.V Fig. 2 is a transverse sectional View of Fig. 1. Fig. 3 is a detail sectional view on line 3 of Fig. 2. Fig. 4 is an enlarged sectional view showing the means for effecting a tight joint at the vouter edge ofthe slot when the shutter is closed. Fig. 5 is asectional detail view showing the manner of closing the slot when the shutter is open. Fig. 6 is a detaill perspective of part of the outer edge of the shutter, showing a ring or loop adapted to be gripped in closing the shutter. Fig. 7 is a lwindow-opening. ltive showmg one of the shutter-supporting perspectivev view of the .metallic frame which extends up the sides and across the top of the Fig. 8 is a detail perspecrollers and its rail. Fig. 9 is a detail perspective showing the catch for holding the shutters tightly together when closed. Fig. 10 is a view similar to Fig. 2, showingamodified structure. Fig. 11 is a detail ofthe right-hand shutter of Fig. 10, and Fig. 12 is a detail of a turn-button shown in Fig. 10.

2 is the stone sill of a window-opening in-v clined outward from the windows, as shown 1n Flg. 3, to glve a fall for dralning off water.

'At its extreme ends, however, the upper face of the sill is not inclined, thereby forming a' ridge 3 across each end under the projecting and overhanging edge of the wall, thereby preventing water (in the case of a driving rain, for example) from finding its way' beyond the ends of the Vsill and into the recesses and wall. Therinner edges of ridges 3 are dished or curved down to theinclined surface of the sill, as shown at 4, Fig. l.'

5 5 are recesses or chambers in the wall along the sides of the window-opening adapted to receive the shutters when the latter are opened. The width of these recesses iissuch as to permit the slight lateralA movement yof the shutters, referred to hereinafter. AI'nuch shallower recess 6 (see dotted lines, Fig. 1) extends across the top of'the'window-open?t ing to provide space in Iwhich the rollers 7'o'n the shutters run on a rail 8.

9 is a metallic frame (see Fig. 7 resting' at its lower ends upon sill 2 near the ridge's:

(see Fig. 1) and extending up both sidesand across the top of the window-opening;v "Said frame is secured in any suitable manner tofthe' wall. v

10 10 are slots extending up the sides of frame 9 and part way across the top, through or in which slots the shutters l1 11 move into and out of the recesses or chambers 5 5 yand 6.

IOO

Across the outer edge of each shutter is a flange 16, having inclined edges. The horn 17 of a cam-lever 18, pivote-d to the inside of one shutter, works through slots 19, Fig'. 9, in flanges '16 to engage a pin 2O on the other shutter, and thereby tightly clamp the meeting edges of the shutters (the flanges 16 16) .tightly together when the latter are closed.

The cam-lever and pin are of such dimensions as to readily pass through slots 1() when the shutters are opened.

Referring to Fig. 4, 21 is an arm located in a pocket 22 in the'wall, having at one end a head 23, which fits into a recess in the inner face of the frame 9, and at its other end a foot 24, having an inclined edge. A screw 25 rigidly seeures the arm to the frame. When the shutter is closed to its full extent, the inclined edge of the foot bears against a knob or projection 26 on the shutter, forcing the latter outwardly and causing it to bear tightly against the outer edge of slot 10, and thus form a tight joint, preventing lire, rain, or the like from entering recess 5 when the shutter is closed. As shown in Fig. 1, there are four sets of arms21 and knobs 26. two sets for each shutter. To allow for this lateral movement of the shutters, each roller 7 and the space between the arms of its hanger 27 are .Wider than the rail 8. By extending down on opposite sides of the rail to the door `the arms of the hanger prevent disengagement of the roller and rail.

When the shutters are opened, the flanges 16 fit into the eountersink of the slots 10 10, closing the latter to exclude rain, dust, &c., and givinga neat iiush finish to the inner edge of the window-opening, Fig. 5. The inclined edges of the iianges 16 by contacting with the inclined shoulders 12 properly center the shutters in the slots and form tight joints.

The iireproof or fire-resisting shutters may be made of sheet metal, as shown in Figs. 1 to 4, of Wood covered with thin sheet metal, as shown in Figs. 5 and 6, or in any other suitable way.

In Fig. 6 I have shown a loop or eye 2S projecting into a semispherical cavity in the edge of the shutter and adapted to be engaged by one or more lingers to pull the shutterout of its recess when it is desired to close the same.

The. above description applies to the modified construction shown in Fig. 10 with the following exceptions: rIhe left-hand shutter 30 has no flange at its outer edge; but the slot 10, through which it moves, is adapted to be closed (when the shutter is opened) by the cover 31, hinged to frame 9 at 32, and adapted to be secured in its closed position by a turn-button 33, Fig. 12.

35 is a flange hinged at 36, Figs. 10 and 11, to the outer edge of the right-hand shutter 34, adapted to be turned to the position shown in dotted lines, Fig. 10, and close slot 10 when the shutter is open or to be turned to the position shown in full lilies and lap the joint between the shutters when the latter are closed.

As will be apparent, the cover 31 at the left of Fig. 1() could be dispensed with and shutter 30 also provided with a hinged flange similar to 35, but adapted to swing inwardly and lap the ljoint on the inside when the shutters are closed. Likewise both shutters could be without a flange, and two doors 31 provided for closing the slots 10 at the opposite sides of the window-opening.

40, Figs. 2 and 10, is the usual windowframe, in which lower and upper windows 41 and 42 are adapted to slide.

I/Vhile I have illustrated and described preferred embodiments. it is to be understood that extensive modifications and changes may be made without departing from the nature and principle of the invention. Likewise some of the novel features may be omitted while still employing others. For example, other equivalent means may be substituted for the arms 21 and knobs 26. W'hile the slots 10. leading into the recess 5, are preferably formed in frame 9, said frame may be enti rely omitted, the slots in that event being the outer open ends of the recesses. The transverse dimensions of the recesses may be the same as those of the slots.

While I have referred particularly to the use of the shutters for closing window-openings outside of the windows, they may be also employed for closing` door-openings outside of the combustible doors ordinarily. used. Furthermore, only one shutter may be employed, as in the case of narrow openings.

What I claim as new is- 1. The combination with the wall of a building having a window or analogous opening therethrough, a recess or chamber extending laterally into said wall from the edge of said opening, means for closing the opening under ordinary conditions, and a lireproof or {ireresisting shutter adapted to move into and out of said recess to open and close said opening outside of the ordinary-closing means.

2. The combination with the wall of a building having' a window or analogous opening therethrough, a recess or chamber extending back into said wall from the edge of said opening, a shutter adapted to move freely into and out of said recess, and means for closing the slot leading into said recess when the shutter is open.

3. rIhe combination with the wall of abuilding having a window or analogous opening therethrough, a recess or chamber extending back into said wall from the ed ge of said opening, a shutter adapted to move freely into and out of said recess, and means on the shutter for closing the slot leading into said recess when the shutter is open.

Window'- opening, and closing means fitting into the countersink and extending across the slot -to close the same When the shutter is open. Y

9. rl`he combination with the Wall of abuilding having a Window or analogous opening therethrough, a shutter adapted to move freely through a countersunk slot at the edge ofthe Window-opening' and means forcing said shutter against the outer edge of the slot to form a tight joint When the shutter is closed.

The combination with the Wall of a building havinga Window or analogous opening therethrough, a shutter adapted to move freely through a countersunk slot at the edge of the Window-opening, and a fixed inclined surface acting against a projection on the shutter to force the latter against the outer', edge of the slot to form a tight joint when tending back into said Wall at the edge of the recess, a projection on the shutter near its inner end, and a fixed inclined surface in the recess near its open end acting against said y projection to force the shutter against the edge lof the slot at the open end of the recess to form a tight joint When the shutter is closed.

13. The combination with the Wall of a building having a Window or analogous opening therethrough, a recess lor chamber extending back into said Wall at the edge of the opening, a metallic plate extending along the edge of the opening and having a slot therethrough leading into the recess, and a shutten adapted to move into and out of said recess through said slot.
